The specific implementation modes of the present disclosure are described below with reference to the drawings. The drawings are as following.
In related technologies, an electric control box is provided with a heat dissipation plate and an installation plate. A surface of the installation plate is provided with an electronic element, and the heat dissipation plate is provided at a surface of the installation plate facing away from the electronic element. Heat generated by the electronic element during operation is first transferred to the installation plate, and then transferred to the heat dissipation plate to achieve heat dissipation of the electronic element. However, during the operation of the electronic element inside the electric control box, the generated heat will increase a temperature of air inside the electric control box. When the temperature of the air is higher than a temperature of the heat dissipation plate by a value and the air has a humidity level, water molecules in the air will form condensate water when they are in contact with the heat dissipation plate. After the condensate water coming into contact with the electronic element inside the electric control box, it is easy to cause damage to the electronic element inside the electric control box.
In view of this, in a heat dissipation plate for an electric control box in an embodiment of the present disclosure, a heat dissipation plate body is provided with a heat dissipation convert plate, and an accommodation area can be formed between two heat dissipation convert plates, and a temperature-and-humidity sensor is provided in the accommodation area. By using the temperature-and-humidity sensor to detect temperature and humidity in an area near the heat dissipation plate, temperature of the heat dissipation plate is controlled to prevent formation of condensate water on the heat dissipation plate and avoid damage to the electronic element inside the electric control box due to a contact with the condensate water.
The following will provide a clear and complete description of the embodiments of the present disclosure in combination with the drawings. The described embodiments are only a part of the embodiments of the present disclosure, not all of them.
As shown in
An accommodation area 170 is formed between two adjacently arranged heat dissipation convert plates 120 on the heat dissipation plate 100, and a temperature-and-humidity sensor 160 is provided within the accommodation area 170. The temperature-and-humidity sensor 160 can detect temperature and humidity in an area near the heat dissipation plate 100. By detecting the obtained temperature and humidity conditions, it can be determined whether air inside the electric control box meets a condition for forming condensate water. Based on this, a heat exchange rate between the heat exchanger 200 and the heat dissipation plate 100 is adjusted, then temperature of the heat dissipation plate 100 is adjusted to allow for a smaller temperature difference between the heat dissipation plate 100 and the air inside the electric control box, to avoid the formation of condensate water after the air inside the electric control box coming into contact with the heat dissipation plate 100.
According to the heat dissipation plate 100 for the electric control box provided in the embodiments of the present disclosure, the temperature and humidity in the area near the heat dissipation plate 100 is detected through the temperature-and-humidity sensor 160 on the heat dissipation plate body 110, and the detected temperature data and humidity data are used to adjust the heat exchange rate between the heat exchanger 200 and the heat dissipation plate 100, and based on this, the temperature of the heat dissipation plate 100 is indirectly adjusted to reduce the temperature difference between the heat dissipation plate 100 and the air inside the electric control box; the condition for the formation of condensate water cannot be met when the air inside the electrical control box comes into contact with the heat dissipation plate 100; to avoid the formation of condensate water on a surface of the heat dissipation plate 100 and preventing the electronic element inside the electric control box to be damaged.
In addition, the accommodation area 170 is a marginal area between two heat dissipation convert plates 120. Providing the temperature-and-humidity sensor 160 in the accommodation area 170 can save space occupied by the temperature-and-humidity sensor 160 on the heat dissipation plate 100. In one embodiment, the accommodation area 170 also provides space for placing connection wires of the temperature-and-humidity sensor 160, and the connection wires of the temperature-and-humidity sensor 160 can be arranged within the accommodation area 170, to facilitate the wiring of the temperature-and-humidity sensor 160.
In addition, in order to prevent the temperature-and-humidity sensor 160 from obstructing a contact between the heat dissipation convert plate 120 and the ready-for-heat-dissipation electronic element in the electric control box, a detection end of the temperature-and-humidity sensor 160 in the accommodation area 170 should not be higher than an end face of the heat dissipation convert plate 120 facing away from the heat dissipation plate body 110, where the end face is a heat exchange contact surface 120a between the heat dissipation convert plate 120 and the electronic element to be heat dissipated. That is to say, the highest point of the detection end of the temperature-and-humidity sensor 160 in the accommodation area 170 will not be raised from the heat exchange contact surface 120a of the heat dissipation convert plate 120. In this way, the temperature-and-humidity sensor 160 will not obstruct the contact between the heat dissipation convert plate 120 and the electronic elements to be heat dissipated, and the heat dissipation convert plate 120 can fully exchange heat with these electronic elements to be heat dissipated, rendering a decrease in the temperature of these electronic elements to be heat dissipated.
Furthermore, since the contact between the heat dissipation convert plate 120 and the ready-for-heat-dissipation electronic elements in the electric control box is not obstructed by the temperature-and-humidity sensor 160, a connection between the heat dissipation plate 100 and these electronic elements to be heat dissipated can also be simplified, which facilitates the assembly of the electric control box.

As shown in
The drainage surface 121 can surround the edge of the heat dissipation convert plate 120, or be arranged at an edge of a side or edges of several sides of the heat dissipation convert plate 120, and it can be arranged according to an actual scene of the heat dissipation plate 100 during use. Due to the fact that the movement of condensate water is mainly driven by gravity, generally speaking, the drainage surface 121 is arranged in a direction facing gravity, and it is easier for the condensate water to flow to the drainage surface 121.
In one embodiment, the drainage surface 121 is an arc chamfer arranged on an outer circumferential edge of the heat exchange contact surface 120a, and two opposite sides at the outer circumferential edge of the heat exchange contact surface 120a are provided with a drainage surface, respectively.
In the embodiments of the present disclosure, a position of the temperature-and-humidity sensor 160 relative to the drainage surface 121 may be arranged in various ways.
As shown in
As shown in
Furthermore, as shown in
For example, the temperature-and-humidity sensor 160 close to the drainage surface 121 of the heat dissipation convert plate 120 detects that condensate water has formed, but the temperature-and-humidity sensor 160 far away from the drainage surface 121 of the heat dissipation convert plate 120 detects that the temperature and humidity near the heat dissipation plate 100 are insufficient to form a harmful amount of condensate water for the electronic element inside the electric control box, the formed condensate water can be quickly discharged, and then there is no need to issue a warning message outwards.
For example, the temperature-and-humidity sensor 160 close to the drainage surface 121 of the heat dissipation convert plate 120 detects that condensate water has not been formed, but the temperature-and-humidity sensor 160 far away from the drainage surface 121 of the heat dissipation convert plate 120 detects that the temperature and humidity near the heat dissipation plate 100 are sufficient to form a harmful amount of condensate water for the electronic element inside the electric control box, and condensate water is about to be rapidly formed on the heat dissipation plate 100, then a warning message will be issued outwards to inform the user that a high amount of condensate water is about to form in the electric control box and there is a risk of damage to the electronic element inside the electric control box.
As shown in
The bottom of the drainage groove 130 can be a flat surface, a concave wedge-shaped surface, or a concave curved surface. When the bottom of the drainage groove 130 is a flat surface, the drainage groove 130 is easier to manufacture; when the bottom of the drainage groove 130 is a concave wedge-shaped surface or a concave curved surface, it is easier for condensate water to flow into the drainage groove 130 along a side wall of the drainage groove 130, which can accelerate the collection of the condensate water and render it accumulate into water droplets or a stream of water, and then be discharged from the drainage groove 130 fleetly.
In a specific application, after the heat dissipation plate 100 is assembled in the electric control box, a drainage direction of the drainage groove 130 is consistent with the gravity direction. This setting allows the condensate water entering the drainage groove 130 to flow along the drainage groove 130 under an action of gravity, which accelerates the discharge of these condensate water in the drainage groove 130 from the heat dissipation plate 100.
As shown in
An extension direction of the block 140 is consistent with the drainage direction of the drainage groove 130, the drainage groove 130 is formed between a side wall of the block 140 and a side wall of an adjacent heat dissipation convert plate 120. A surface of the block 140 facing away from the heat dissipation plate body 110 is flush with a surface of the heat dissipation convert plate 120 facing away from the heat dissipation plate body 110, and when the heat dissipation plate 100 is assembled in the electric control box, the block 140 can also contact the ready-for-heat-dissipation electronic element in the electric control box, to increase a contact area between the heat dissipation plate 100 and the ready-for-heat-dissipation electronic element in the electric control box, and improving a heat dissipation effect of the heat dissipation plate 100.
The heat exchanger 200, to a certain extent, can function to regulate the temperature of the heat dissipation plate 100, as the heat dissipation plate 100 itself is used to exchange heat with the to-be-heat-dissipated electronic elements in the electric control box, and transfer the heat absorbed by these to-be-heat-dissipated electronic elements to the heat exchanger 200. The principle of heat exchange for the heat dissipation plate 100 is to utilize a temperature difference between the heat dissipation plate 100 itself and the ready-for-heat-dissipation electronic elements in the electric control box, to render transfer of heat on these electronic elements for heat dissipation to the heat dissipation plate 100, thus the heat dissipation plate 100 itself does not a have temperature regulation function. The temperature of the heat dissipation plate 100 depends on the heat exchange efficiency of the heat exchanger 200 to the heat dissipation plate 100 and the temperature of the electronic elements to be heat dissipated. Therefore, the heat exchange rate of the heat exchanger 200 to the heat dissipation plate 100 can be changed by adjusting the power of the heat exchanger 200, and in turn a cooling rate of the heat dissipation plate 100 can be adjusted, achieving indirect regulation of the temperature of the heat dissipation plate 100.
The heat exchanger 200 in the present disclosure can be a microchannel heat exchanger 200. The microchannel heat exchanger 200 includes at least two sets of microchannels. The at least two sets of microchannels include multiple first microchannels for flowing a first refrigerant stream and multiple second microchannels for flowing a second refrigerant stream. The second refrigerant stream absorbs heat from the first refrigerant stream to render undercooling of the first refrigerant stream, or the first refrigerant stream absorbs heat from the second refrigerant stream to render undercooling of the second refrigerant stream.
The microchannel heat exchanger 200 in the embodiments of the present disclosure can also serve as an economizer for an air conditioner. In this way, the microchannel heat exchanger 200 can be used to cool the electronic element inside the electric control box and also serve as the economizer, to avoid a need to additionally provide an economizer outside the electric control box, to simplify the structure of the air conditioner, save space and costs.
In a specific application, the temperature-and-humidity sensor 160 of the heat dissipation plate 100 detects the temperature and humidity in an area near the heat dissipation plate 100. When the temperature-and-humidity sensor detects that the temperature and humidity in the area near the heat dissipation plate 100 meet a condition for the formation of condensate water, the power of the heat exchange component 200 may be reduced, to reduce the heat exchange rate of the heat exchanger 200 to the heat dissipation plate 100, which renders that the temperature of the heat dissipation plate 100 rises and that the temperature difference between the heat dissipation plate 100 and the air inside the electric control box be smaller, thus the air inside the electric control box is unable to meet the condition for the formation of condensate water when it comes into contact with the heat dissipation plate 100, preventing the formation of condensate water on the surface of the heat dissipation plate 100 and avoiding damage to the electronic elements inside the electric control box.
The heat exchanger 200 can be a heat dissipation tube arranged on a side of the heat dissipation plate 100 away from the heat dissipation convert plate 120. The heat dissipation plate 100 is in direct contact with a surface of the heat exchange tube, and a cooling medium is circulating and flowing inside the heat exchange tube.
When in use, the cooling medium circulating and flowing inside the heat exchange tube continuously exchanges heat with the heat exchange tube. The heat exchange tube contacts the heat dissipation plate 100 for heat exchange, which allows the heat on the heat dissipation plate 100 to be transferred to the cooling medium inside the heat exchange tube through the heat exchange tube, and the heat to be taken away from the electric control box through the circulation and flow of the cooling medium.
The heat exchanger 200 can also be a plate-type heat exchanger. The plate-type heat exchanger is a plate body with a flat surface, and a heat dissipation channel for the flowing of the cooling medium is provided inside the plate-type heat exchanger. The heat exchanger 200 is adhered to a surface on a side of the heat dissipation plate 100 away from the heat dissipation convert plate 120.
When in use, the cooling medium is circulating and flowing in the heat dissipation channel, the cooling medium that circulates and flows inside the heat dissipation channel continuously exchanges heat with a shell of the plate-type heat exchanger. The shell of the plate-type heat exchanger contacts the heat dissipation plate 100 for heat exchange, which allows the heat on the heat dissipation plate 100 to be transferred, through the shell of the plate-type heat exchanger, to the cooling medium inside the heat exchange tube, and the heat to be taken away from the electric control box through the circulation and flow of the cooling medium.
Compared to the heat exchange tube, the plate-type heat exchanger, with a surface that is a plane surface, can be adhered more closely to the surface of the heat dissipation plate 100, which increases a contact area between the heat dissipation plate 100 and the plate-type heat exchanger, and renders the heat exchange in each area on the heat dissipation plate 100 more evenly, thus achieving a better heat exchange effect with the heat dissipation plate 100.
Furthermore, due to the fact that the surface of the plate-type heat exchanger can be adhered more closely to the surface of the heat dissipation plate 100, compared to the heat exchange tube, the plate-type heat exchanger can make full use of the cooling medium and reduce the waste of the cooling medium.
In one embodiment, the cooling medium circulating and flowing in the heat exchange tube and in the heat dissipation channel of the plate-type heat exchanger can be a fluid medium such as pure water, butene, ethylene glycol, etc.
Due to the fact that the heat dissipation component in the embodiments of the present disclosure adopts all embodiments of the heat dissipation plate for the electric control box in the embodiments of the present disclosure, the heat dissipation component in the embodiments of the present disclosure has at least all the beneficial effects of the heat dissipation plate for the electric control box, and details will not be repeated here.

A surface of the installation plate 400 facing away from the heat dissipation plate 100 is used to install the electronic elements to be heat dissipated. The electronic elements to be heat dissipated can include a reactor, a filter board, and other electronic elements generating heat during operation that are mounted in the electric control box. In this way, the heat generated by the electronic elements to be heat dissipated will first be transferred to the installation plate 400, and then heat will be exchanged between the installation plate 400 and the heat dissipation plate 100 to transfer the heat to the heat dissipation plate 100. The heat on the heat dissipation plate 100 will come into contact with the heat exchanger 200 for heat exchange, and finally the heat will be discharged from the accommodation cavity through the cooling medium inside the heat exchanger 200.
It can be understood that the accommodation cavity of the box body 300 can also be provided with a circuit board, a connection cable, and other components that support the electric control box to achieve an electronic control function. A through hole (not shown) can be provided at a side wall of the box body 300, and the connection cable in the accommodation cavity of the box body 300 can be led out to the outside of the box body 300 through the through hole. An inlet pipeline and an outlet pipeline of the heat dissipation tube in the accommodation cavity of the box body 300 can also be led out to the outside of the box body 300 through the through hole.
It should be noted that in order to ensure the sealing of the box body 300, sealing is required among the connection cable, the inlet and outlet pipelines of the heat dissipation tube, and the through-hole. For example, a sealant can be provided among the connection cable, the inlet and outlet pipelines of the heat dissipation tube, and the through-hole, which ensures that the box body 300 is a sealed box body, to ensure the sealing of the electric control box.
In a specific application, an installation sequence of the heat exchanger 200, the heat dissipation plate 100, and the installation plate 400 in the accommodation cavity of the box body 300 can also be adjusted according to an actual need. For example, the heat exchange tube, the heat dissipation plate 100, and the installation plate 400 can be arranged in layers sequentially in a direction pointing from the box cover 320 to a bottom wall of the bottom box 310.

In a specific application, a surface of the heat dissipation convert plate 120 facing away from the heat dissipation plate body 110 can be a plane surface, and a bottom surface of the element to be heat dissipated can also be a plane surface. This allows the surface of the heat dissipation convert plate 120 facing away from the heat dissipation plate body 110 to fit with the bottom surface of the element to be heat dissipated, to increase a contact area between the heat dissipation plate 100 and the element to be heat dissipated, and further improve the heat dissipation effect of the heat dissipation plate 100.
In addition, there can be multiple limit convert plates 150; the multiple limit convert plates 150 are arranged to be spaced apart on the heat dissipation plate body 110. This can enable more heat dissipation convert plates 120 to come into contact with the bottom surface of the ready-for-heat-dissipation element mounted on the installation plate 400, to improve the heat exchange efficiency between the heat dissipation plate 100 and the ready-for-heat-dissipation element.
Each one of the multiple limit convert plates 150 is provided with two heat dissipation convert plates 120; and on the same limit convert plate 150, two heat dissipation convert plates 120 are arranged to be spaced apart on the heat dissipation plate body 110. Two adjacently arranged heat dissipation convert plates 120 on the same limit convert plate 150 have an accommodation area 170 formed therebetween, and the accommodation area 170 formed between the two adjacently arranged heat dissipation convert plates 120 is provided with a temperature-and-humidity sensor 160. In this way, each limit convert plate 150 being provided with two heat dissipation convert plates 120 can reduce the number of limit notches 410 on the installation plate 400, improve the strength of the installation plate 400, and reduce the processing difficulty of the installation plate 400. In one embodiment, the accommodation area 170 formed between the two adjacently arranged heat dissipation convert plates 120 being provided with the temperature-and-humidity sensor 160 is equivalent to that each limit notch 410 is provided with the temperature-and-humidity sensor 160. This enables the temperature-and-humidity sensor 160 in each limit notch 410 can detect the temperature and humidity near a contact area between the heat dissipation plate 100 and each electronic element to be heat dissipated, to more accurately detect whether there is a risk of forming condensate water in each area of the heat dissipation plate 100.

Both the box body 110 and the box cover 111 can be sheet metal parts, and there are no specific restrictions on the material and processing technology of the box body 110 and the box cover 111.
It should be noted that the electric control box 100 of this embodiment can be a sealed electric control box, for example. This can prevent water droplets, dust, and other foreign objects from entering the electric control box to cause damage to the electronic element inside the electric control box; and thus, achieving waterproof, dustproof, and anti-corrosion effects.
The electric control box 100 provided in this embodiment further includes a retaining plate 120 and a heat dissipation plate component 130. The heat dissipation plate component 130 is detachably connected to a bottom of the box main body 112; a side of the heat dissipation plate component 130 facing the opening 1121 is provided with the retaining plate 120. The retaining plate 120 is used for providing different types of electronic elements, and is connected to a connector 131 of the heat dissipation plate component 130; a detachable connection with the heat dissipation plate component 130 can be achieved through the connector 131. When it is necessary to replace or repair an electronic element on the retaining plate 120, the retaining plate 120 can be removed from the heat dissipation plate component 130 to replace or repair the electronic element.

As shown in
The heat dissipation plate component 130 provided in this embodiment is provided with the connection hole 1321; where the connector 131 with the threaded installation hole 1311 is embedded in the connection hole 1321. The retaining plate 120 is detachably connected to the connector 131 through the threaded installation hole 1311 to achieve a detachable connection between the retaining plate 120 and the heat dissipation plate component 130. Therefore, it is possible to avoid a threaded hole to be provided directly on the heat dissipation plate 132, and a reliable connection between retaining plate 120 and heat dissipation plate component 130 can be achieved.
It should be noted that an inner wall of the connection hole 1321 mentioned above is a rotation surface, which means that the connection hole 1321 is an unthreaded hole. Compared to the threaded hole provided on the heat dissipation plate 132, providing the unthreaded hole on the heat dissipation plate 132 is easier to achieve in terms of process, which facilitates the processing and forming of the heat dissipation plate 132.
Furthermore, in this embodiment, the threaded installation hole 1311 mentioned above may have a pitch of 3 mm or 4 mm, or there may be other pitches that match the heat dissipation plate 132, no specific restrictions will be made to the axial and radial lengths of the connector 131.
In order to arrange the connector 131 on the heat dissipation plate 132, in this embodiment, the connector 131 is connected to the connection hole 1321 by means of clamping.
In one embodiment, the connector 131 can be press-fitted into the connection hole 1321 through press-fit equipment, such as riveting, inlaying, or spinning method. In this embodiment, there is no restriction on the specific press-fit method of the connector 131, as long as it can be ensured that the connector 131 is reliably press-fitted into the connection hole 1321.
In order to enable the connector 131 to be firmly fitted with the connection hole 1321, in a specific implementation mode of this embodiment, a circumferential side wall of the connector 131 is closely engaged with a side wall of the connection hole 1321. In this way, the connector 131 can be reliably fitted with the wall of the connection hole 1321, protecting the connector 131 from escaping from the connection hole 1321 after its movement.

In some implementation modes, the first end face 1312 and a plate surface of the heat dissipation plate 132 can be in the same plane, the first end face 1312 can also be arranged outside the plate surface of the heat dissipation plate 132, the second end face 1313 can be flush with a bottom of the connection hole 1321, or can be arranged on a side where the bottom of the connection hole 1321 faces the opening of the connection hole 1321.
In order to improve the overall aesthetics of the heat dissipation plate component 130 and reduce occupied space of the heat dissipation plate component 130, in this embodiment, the first end face 1312 and the plate surface of the heat dissipation plate 132 are on the same plane, and the second end face 1313 is arranged inside the connection hole 1321. That is to say, there is a distance between the second end face 1313 and the bottom of the connection hole 1321 in an axial direction of the connection hole 1321. In this way, by flushing the first end face 1312 with the plate surface of the heat dissipation plate 132, the surface of the heat dissipation plate 132 can be flat without any protruded structures, to improve the overall aesthetics of the heat dissipation plate component 130.
In one embodiment, for ease of explanation, a maximum radial length of the first end face 1312 in a radial direction of the threaded installation hole 1311 can be defined as a first maximum radial length, and a maximum radial length of the second end face 1313 is defined as a second maximum radial length. In order to press-fit the connector 131 into the connection hole 1321, in this embodiment, the first maximum radial length is greater than the second maximum radial length. Therefore, it is convenient to press-fit the connector 131 into the connection hole 1321, and to improve the smoothness of the connector 131 during installation.
In order to further improve the reliability of a connection between the connector 131 and the connection hole 1321, the connector 131 itself can have an anti-rotation function. The following will provide a detailed introduction to the connector 131 in the heat dissipation plate component 130 provided in this embodiment.

It should be noted that the non-circular surface here can be of different shapes such as a polygon shape or a polygon-like shape. The polygon-like shape here can be a shape formed by connecting two adjacent sides in a polygon through an arc line, and each anti-rotation unit 1314 has a maximum radial length in a radial direction of the threaded installation hole 1311. The maximum radial length of each anti-rotation unit 1314 gradually decreases in a direction from the first end face 1312 to the second end face 1313. In this way, not only it is convenient to press-fit the connector 131 into the connection hole 1321, but also the connector 131 can be prevented from rotating in the connection hole 1321, which renders the press-fit connection between the connector 131 and the connection hole 1321 more reliable.
In one embodiment, the anti-rotation unit 1314 has multiple anti-rotation parts 13141, a distribution direction of the multiple anti-rotation parts 13141 is consistent with a circumferential direction of the connector 131, and only the multiple anti-rotation parts 13141 in the anti-rotation units 1314 close to the second end face 1313 are arranged to be adjacent to each other. In the remaining anti-rotation units 1314, the multiple anti-rotation parts 13141 are arranged to be spaced apart, and the anti-rotation parts 13141 have outer circumferential edges which are non-circular edges. By setting the anti-rotation parts 13141 with the outer circumferential edges being non-circular edges, a friction force between the connector 131 and the connection hole 1321 can be increased, and the rotation of the connector 131 in the connection hole 1321 can be prevented.
In order to facilitate the processing of the anti-rotation part 13141 and the processing and forming of the connector 131, in this embodiment, the anti-rotation part 13141 has an outer edge surface along its circumference side, and an extension direction of the anti-rotation part 13141 along its outer circumferential edge surface is consistent with an extension direction of a plane surface, and an outer contour of a projection surface of the anti-rotation unit 1314 is polygonal in an axial direction of the connection hole 1321. In this way, it is convenient to process the outer circumferential edge surface of the anti-rotation part 13141, to facilitate the processing of the anti-rotation part 13141 and facilitate the processing and forming of the connector 131.
In order to protect the heat dissipation plate 132 from an excessive deformation under a condition that the anti-rotation unit 1314 can play an effective anti-rotation effect, in this embodiment, the anti-rotation unit 1314 has a projection surface in the axial direction of the connection hole 1321, and the projection surface of the anti-rotation unit 1314 has multiple maximum radial edges. In this embodiment, multiple maximum radial edges coincide on the same circumference, and in addition, in the axial direction of the connection hole 1321, the projection surfaces of the anti-rotation units 1314 have maximum radial edges; and the maximum radial edges of the projection surfaces of the individual anti-rotation units 1314 are arranged on circumferences that are equal. Here, the circumferences being equal can render an interpretation that the circumferences where the maximum radial edges of the projection surfaces of the individual anti-rotation units 1314 in the axial direction of the connection hole 1321 are arranged are the same circumference. In this way, not only the heat dissipation plate 132 can be prevented from excessive deformation, but also the maximum radial edges of the individual anti-rotation units 1314 can maintain consistency in shape, facilitating the processing and forming of the anti-rotation units 1314.
Furthermore, in the circumferential direction of the connector 131, multiple anti-rotation parts 13141 are symmetrically distributed; the multiple anti-rotation parts 13141 are uniformly distributed. In this way, during the process of processing and manufacturing the anti-rotation units 1314, it is not only convenient to determine a position of each anti-rotation part 13141, but also convenient to process and manufacture each anti-rotation part 13141.
Furthermore, in order to facilitate the combination and connection of various anti-rotation units 1314 together, in this embodiment, the anti-rotation parts 13141 in each anti-rotation unit 1314 have the same position in the circumferential direction of the connector 131. That is to say, if at a determined position of the connector 131 in the circumferential direction thereof, there is an anti-rotation part 13141 of a anti rotation unit 1314, then along an axial direction of the threaded installation hole 1311, there are also anti-rotation parts 13141 of other anti-rotation units 1314 at this position.
In order to enable the anti-rotation part 13141 to have an effective anti-rotation effect, special restrictions have been made on a structure of the anti-rotation part 13141 in this embodiment. The following is a detailed introduction to the structure of the anti-rotation part 13141.
As shown in
In order to prevent the connector 131 from moving in an axial direction of the connection hole 1321; in a specific implementation mode of this embodiment, the anti-rotation part 13141 further has a stop surface 131412 which is provided on a side of the guide surface 131411 facing away from the second end face 1313, and an extension direction of the stop surface 131412 is consistent with a radial direction of the connection hole 1321. In this way, by providing the stop surface 131412, a relative position between the connector 131 and the heat dissipation plate 132 can be limited in the axial direction of the connection hole 1321, to prevent the connector 131 from moving in the axial direction of the connection hole 1321.
In one embodiment, the stop surface 131412 is parallel to the first end face 1312, which means that the stop surface 131412 is parallel to the second end face 1313. This facilitates the processing and forming of the anti-rotation part 13141, and reduces the manufacturing cost of the connector 131.
In order to improve the structural stability of the connector 131, the connector 131 further includes a first support portion 1315 and, furthermore, the connector 131 further includes a second support portion 1316, and the first support portion 1315 is arranged opposite to the second support portion 1316.
In one embodiment, in the axial direction of the threaded installation hole 1311, the first support portion 1315 positionally corresponds to the first end face 1312, and the second support portion 1316 positionally corresponds to the second end face 1313, and the first end face 1312 is formed at an end of the first support portion 1315 facing away from the second support portion 1316, and the second end face 1313 is formed at an end of the second support portion 1316 facing away from the first support portion 1315; multiple anti-rotation units 1314 are arranged between the first support portion 1315 and the second support portion 1316. In this way, by providing with the first support portion 1315 and the second support portion 1316, it is possible to provide a support for multiple anti-rotation units 1314 and improve the structural stability of the connector 131.
In a specific implementation mode of this embodiment, in the axial direction of the connection hole 1321, an outer contour of a projection surface of the first end face 1312 is a first outer contour, and an outer contour of a projection surface of the second end face 1313 is a second outer contour. The first outer contour is circular, and the second outer contour is polygonal. In some other implementation modes, the first outer contour and the second outer contour can also be in other shapes, there are no specific restrictions on the shape of the first and second outer contours.
Furthermore, the connector 131 further has multiple connection parts 1317 that are arranged to be spaced apart in the axial direction of the connection hole 1321. The number of connection parts 1317 is the same as the number of anti-rotation units 1314, and the connection parts 1317 correspond to the anti-rotation units 1314. In a specific implementation mode of this embodiment, a connection part 1317 is arranged between the first support portion 1315 and the anti-rotation unit 1314 close to the first support portion 1315, the remaining connection parts 1317 are arranged between two adjacently arranged anti-rotation units 1314. This renders the structure of the connector 131 more stable.

In the electric control box 100 provided in this embodiment, during an assembly process of the electric control box 100, when the heat dissipation plate component 130 is connected with the retaining plate 120 for installation, the connector 131 is firstly aligned with the connection hole 1321 on the heat dissipation plate 132, and then the connector 131 is press-fitted into the connection hole 1321 through press-fit equipment, to render a top surface of the connector 131 to be flush with a plate surface of the heat dissipation plate 132. Then, the retaining plate 120 is placed on the heat dissipation plate component 130, threaded fasteners with the same number of connection holes 1321 are used, such as screws, to make the threaded fasteners penetrate through the retaining plate 120 and the threaded installation holes 1311 in sequence, to achieve a detachable connection between the heat dissipation plate component 130 and the retaining plate 120.

In the air conditioner provided in this embodiment, the microchannel heat exchanger mentioned above can serve as an economizer of the air conditioner. In this way, the microchannel heat exchanger not only can be used to cool an electronic element inside the electric control box 100, but also serves as the economizer, to avoid a need to additionally provide an economizer outside the electric control box 100 to simplify the structure of the air conditioner, save space and costs.
It should be noted that the air conditioner provided in this embodiment should further include other components or parts to ensure a normal operation of the air conditioner. However, no detailed introduction will be given to other components or parts in the air conditioner provided in this embodiment.

For example, the heat exchange tube component 122 can be mounted in the accommodation cavity 114 of the box body 110 in such a manner that it is close to a bottom wall 112 of the box body 110. The heat dissipation plate 121 can be stacked on a side of the heat dissipation tube component 122 facing away the bottom wall 112, and the installation plate for the electric appliance can be stacked on a side of the heat dissipation plate 121 facing away from the heat exchange tube component 122.

The heat exchange tube component 122 can include one heat exchange tube 1221, two heat exchange tubes 1221, or multiple heat exchange tubes 1221. For example, one heat exchange tube 1221 can be coiled in an “S” shape and form a heat exchange surface, two or more heat exchange tubes 1221 can be arranged in parallel and form the heat exchange surface; the heat dissipation plate 121 covers the heat exchange surface formed by the arrangement of the heat exchange tubes 1221, for heat exchange with the heat exchange tubes 1221.
The accommodation cavity 114 of the box body 110 can also be provided with a circuit board (not shown in the drawing), a connection cable (not shown in the drawing), and other components that support an electronic control function of the electric control box 100. A through hole can be provided on a side wall 113 of the box body 110, and the connection cable inside the accommodation cavity 114 of the box body 110 can be led out to the outside of the box body 110 through the through hole. The heat exchange tube component 122 can include a refrigerant inlet pipeline and a refrigerant outlet pipeline, the refrigerant inlet pipeline and refrigerant outlet pipeline can also be led out to the outside of the box body 110 through the through hole, and part of the structure of the heat exchange tube component is arranged inside the electric control box, and part of the structure extends to the outside of the electric control box 100.
Next, an explanation will be given to the heat dissipation component 120 including the heat exchange tube component 122 and the heat dissipation plate 121. It can be understood that the heat dissipation component 120 in the following description is not limited to being applied to the electric control box 100 of the embodiments of the present disclosure, but can also be applied to other devices that require heat dissipation.
Referring to
The heat dissipation plate 121 is provided with a limit rib 1211 protruding towards a side where the heat exchange tube component 122 is arranged; and an extension direction of the limit rib 1211 is consistent with an extension direction of the heat exchange tube component 122. For example, when the heat exchange tubes of the heat exchange tube component 122 are arranged to be parallel, the extension direction of the heat exchange tube component 122 can be an extension direction of the heat exchange tube. In one embodiment, the extension direction of the heat exchange tube component 122 can also be an extension direction of an edge of the heat exchange tube component 122. In a first possible implementation mode, in the extension direction of the heat exchange tube component 122, the limit rib 1211 can extend in such a manner that its two ends are flush with two ends of the heat dissipation plate 121. In a second possible implementation mode, in the extension direction of the heat exchange tube component 122, the limit rib 1211 can extend in such a manner that one end thereof is flush with an end of the heat dissipation plate 121 and the other end of the limit rib 1211 can extend and stop within a plate surface of the heat dissipation plate 121. In a third possible implementation mode, in the extension direction of the heat exchange tube component 122, both ends of the limit rib 1211 can extend and stop within the plate surface of the heat dissipation plate 121.
In addition, in the extension direction of the heat exchange tube component 122, the limit rib 1211 can include two or more limit rib sections that are arranged to be spaced apart; the multiple limit rib sections can be arranged at an equal interval or an unequal interval. The interval between two or more limit rib sections can be used to avoid a connection structure on the heat exchange tube component 122.
A side surface of the heat exchange tube component 122 facing the limit rib 1211 abuts against a side surface of the limit rib 1211 facing the heat exchange tube component 122; that is, the limit rib 1211 can position the heat dissipation plate 121 and the heat exchange tube component 122 to determine a relative position between the heat dissipation plate 121 and the heat exchange tube component 122. At the same time, a relative angle between the heat dissipation plate 121 and the heat exchange tube component 122 is determined, as so to ensure that the heat dissipation plate 121 and the heat exchange tube component 122 do not tilt after being assembled together.
The limit rib 1211 and the heat dissipation plate 121 are an integrated part. For example, the limit rib 1211 and the heat dissipation plate 121 can be an integrated part formed by machining a piece of material through a turning, milling, planning, grinding, or extrusion forming process. Of course, the limit rib 1211 and the heat dissipation plate 121 can also be formed into an integrated part through other processes.
In one possible implementation mode, the limit rib 1211 is an aluminum limit rib 1211, and the heat dissipation plate 121 is an aluminum heat dissipation plate 121. During the processing, an aluminum sheet can be extruded to form the heat dissipation plate 121 with the limit rib 1211, that is, the limit rib 1211 and the heat dissipation plate 121 are an integrated part formed by extrusion. On the one hand, the extrusion molding process is convenient to operate and is conducive to improving the processing efficiency of the heat dissipation plate 121; on the other hand, the heat dissipation plate 121, formed by extrusion, with a limit rib 1211 not only is conducive to ensuring the reliability of a connection between the limit rib 1211 and the heat dissipation plate 121, but also ensures a certainty of a position of the limit rib 1211 on the heat dissipation plate 121, to facilitate the reliability of mutual positioning between the heat dissipation plate 121 and the heat exchange tube component 122.
The embodiments of the present disclosure involve providing the heat dissipation component 120 which includes the heat exchange tube component 122 and the heat dissipation plate 121, arranging the heat dissipation plate 121 and the heat exchange tube component 122 in layers, and contacting a surface of the heat exchange tube component 122 that faces the heat dissipation plate 121 with a surface of the heat dissipation plate 121 that faces the heat exchange tube component 122, and heat on the heat dissipation plate 121 can be transferred to the heat exchange tube component 122 through a contact surface between the heat dissipation plate 121 and the heat exchange tube component 122, and the heat is dissipated by the heat exchange tube component 122, and heat generated by the electronic element in the electric control box 100 during operation can be transferred outwards through the heat dissipation component 120 to improve the reliability of the operation of the electronic element.
At the same time, a limit rib 1211 is provided on the heat dissipation plate 121, a surface of the limit rib 1211 faces a surface where the heat exchange tube component 122 is arranged, the extension direction of the limit rib 1211 is rendered to be consistent with the extension direction of the heat exchange tube component 122; and the side of the heat exchange tube component 122 facing the limit rib 1211 abuts against the side of the limit rib 1211 facing the heat exchange tube component 122, and the limit rib 1211 can play a positioning role between the heat dissipation plate 121 and the heat exchange tube component 122, to ensure the stability of the position and angle of the heat dissipation plate 121 relative to the heat exchange tube component 122, and to prevent from tilting after assembly. In one embodiment, by providing the limit rib 1211 and the heat dissipation plate 121 as an integral part, it is not only beneficial to reduce the number of parts and simplify the structure of the heat dissipation plate 121, but also to improve the structural strength and reliability of a connection between the limit rib 1211 and the heat dissipation plate 121.
As shown in
In a specific application, when the heat exchange component can be mounted in the accommodation cavity 114 of the electric control box 100, a surface of the heat exchange tube component 122 away from the heat dissipation plate 121 can be mounted towards the bottom wall 112 of the box body 110. At this time, by providing the top of the limit rib 1211 to be lower than the surface of the heat exchange tube component 122 away from the heat dissipation plate 121, or by providing the top of the limit rib 1211 to be flush with the surface of the heat exchange tube component 122 away from the heat dissipation plate 121, which may avoid interference between a protruding height of the limit rib 1211 and the bottom wall 112 of the box body 110, to ensure a smooth installation of the heat exchange tube component 122 and the bottom wall 112 of the box body 110.
As shown in
In one possible implementation mode, it is possible to provide two limit ribs 1211; the two limit ribs 1211 may be provided therebetween with three heat exchange tubes 1221 that are arranged side by side. The two limit ribs 1211 respectively abuts against two sides of the three heat exchange tubes 1221 that are arranged side by side to position the heat dissipation plate 121 on the heat exchange tube 1221; and thus, determining a relative angle and a relative position between the heat dissipation plate 121 and the heat exchange tube component 122.
In another possible implementation mode, it is possible to provide more limit ribs 1211; a heat exchange tube 1221 can be clamped between two adjacent limit ribs 1211. This not only facilitates better locating of a relative angle and a relative position between the heat exchange tube 1221 and the heat dissipation plate 121, but also increases the contact area between the heat exchange tube 1221 and the heat dissipation plate 121 to improve a thermal conductivity effect between the heat exchange tube 1221 and the heat dissipation plate 121.
It can be understood that the number and arrangement of limit ribs 1211, the spacing between two adjacent limit ribs 1211, and the number of heat exchange tubes 1221 clamped between two adjacent limit ribs 1211 are not limited to the two possible implementation modes mentioned above. Setting is possible according to an actual need in a specific application.
As shown in
As an example, seven heat exchange tubes 1221 are included, which, in the plane surface parallel to the heat dissipation plate 121, are parallel to each other and arranged to be spaced apart to form the heat exchange tube component 122. The heat dissipation plate 121 covers the surface of the heat exchange tube component 122 and contacts multiple heat exchange tubes 1221 in the heat exchange tube component 122 at the same time, to facilitate a rapid transfer of heat from different positions of the heat dissipation plate 121 to the heat exchange tubes 1221 of the heat exchange tube component 122, and thus it is beneficial to improve the heat dissipation efficiency of the heat dissipation component 120.
As shown in
In a first possible implementation mode, in the extension direction of the heat exchange tube 1221, both ends of the groove 1212 can extend to both ends of the heat dissipation plate 121. In a second possible implementation mode, in the extension direction of the heat exchange tube 1221, one end of the groove 1212 can extend to an end of the heat dissipation plate 121, and the other end of the groove 1212 can extend and stop within the plate surface of the heat dissipation plate 121. In a third possible implementation mode, in the extension direction of the heat exchange tube 1221, both ends of the limit rib 1211 can extend and stop within the plate surface of the heat dissipation plate 121.
In a specific application, during the process of welding the heat exchange tube 1221 and the heat dissipation plate 121 together, first, a welding flux is applied on the surface of the heat exchange tube 1221 facing the heat dissipation plate 121, and the heat exchange tube 1221 and the heat dissipation plate 121 are fixed together through a fixture or other parts. Then, the fixed heat exchange tube 1221 and the heat dissipation plate 121 are placed together in a heating device for heating, to melt the welding flux, and the heat dissipation plate 121 and the heat exchange tube 1221 are in a welding connection. During a heating process, the groove 1212 on the heat dissipation plate 121 allows for quickly and evenly heating a middle area of the heat dissipation plate 121 along a thickness direction of the heat dissipation plate 121, which is beneficial for improving the quality of welding between the heat dissipation plate 121 and the heat exchange tube 1221.
As shown in
Furthermore, in order to ensure that the strength of the heat dissipation plate 121 at the groove 1212 meets the requirements, the depth of the groove 1212 can be set to be less than or equal to ½ of the thickness of the heat dissipation plate 121. For example, the depth of the groove 1212 can be equal to a half of the thickness of the heat dissipation plate 121, or the depth of the groove 1212 can be equal to one-third of the thickness of the heat dissipation plate 121, or the depth of the groove 1212 can be set to any value that is less than or equal to ½ of the thickness of the heat dissipation plate 121 according to an actual need. Thus, the groove 1212 not only can allow for rapid and evenly heating the heat dissipation plate 121, to achieve the purpose of improving the welding quality, but also it can prevent the structural strength of the heat dissipation plate 121 from being affected due to an excessive depth of the groove 1212; at the same time, it can also prevent the thickness of the heat dissipation plate 121 at the bottom of the groove 1212 from being too small, which may cause overheating during the welding and heating process.
In one possible implementation mode, the heat exchange tube 1221 can be a microchannel flat tube, which has a relatively large flat surface, the heat dissipation plate 121 is in contact with the flat surface of the microchannel flat tube. On the one hand, the flat surface of the microchannel flat tube is conducive to increasing a contact area between the heat exchange tube 1221 and the heat dissipation plate 121, to ensure the heat conduction effect between the heat exchange tube 1221 and the heat dissipation plate 121; on the other hand, the microchannel flat tube not only saves refrigerant consumption, but also have a high heat transfer coefficient and a good heat transfer effect.
In other possible implementation modes, the heat exchange tube 1221 can also be a simple flat tube. The heat dissipation plate 121 contacts and transfers heat to the flat surface of the flat tube, the flat tube is filled with refrigerant to achieve the cooling function of the heat exchange tube 1221. In addition, the heat exchange tube 1221 has a cross-sectional shape including but not limited to a rectangular, a circular, an elliptical, and a trapezoid.
A surface of the heat exchange tube 1221 facing the heat dissipation plate 121 and a surface of the heat dissipation plate 121 facing the heat exchange tube 1221 can be in a welding connection. For example, the surface of the heat exchange tube 1221 facing the heat dissipation plate 121 and the surface of the heat dissipation plate 121 facing the heat exchange tube 1221 are in a welding connection by means of brazing. In respect of the brazing, the deformation is small, and the welding area is flat and beautiful. In one embodiment, the brazing is conducive to ensuring that the surface of the heat exchange tube 1221 facing the heat dissipation plate 121 is in close contact with the surface of the heat dissipation plate 121 facing the heat exchange tube 1221, to not only improve the heat transfer effect between the heat dissipation plate 121 and the heat exchange tube 1221, but also having no need to provide other connection structures, which is beneficial to save space.

The second refrigerant stream absorbs heat from the first refrigerant stream to render undercooling of the first refrigerant stream, or the first refrigerant stream absorbs heat from the second refrigerant stream to render undercooling of the second refrigerant stream.
The microchannel heat exchanger of the embodiments of the present disclosure can also serve as an economizer for an air conditioner. In this way, the microchannel heat exchanger not only can be used to cool an electronic element inside the electric control box, but also serves as the economizer, to avoid a need to additionally provide an economizer outside the electric control box to simplify the structure of the air conditioner, save space and costs.
The electric control box 100 can further include a heat exchange tube 120, a heat dissipation plate 130, and an installation plate 140. The heat exchange tube 120, the heat dissipation plate 130, and the installation plate 140 are all accommodated in the accommodation cavity 114 of the box body 110. As an example, the heat exchange tube 120 can be mounted in the accommodation cavity of the box body 110 on a side close to the bottom wall 112. The heat dissipation plate 130 is stacked on a side of the heat exchange tube 120 facing away from the bottom wall 112, and the installation plate 140 is stacked on a side of the heat dissipation plate 130 facing away from the heat exchange tube 120. The surface of the installation plate 140 facing away from the heat dissipation plate 130 is mounted with an element to be heat dissipated (not shown in the drawing). The element to be heat dissipated can include a press, a fan or other electrical components that generate heat during operation.
It can be understood that an installation sequence of the heat exchange tube 120, the heat dissipation plate 130, and the installation plate 140 in the accommodation cavity 114 of the box body 110 can also be adjusted according to an actual need. For example, the heat exchange tube 120, the heat dissipation plate 130, and the installation plate 140 can be arranged in layers sequentially in a direction pointing from the box cover 111 to the bottom wall 112.
In addition, the accommodation cavity 114 of the box body 110 can further be provided with a circuit board (not shown in the drawing), a connection cable (not shown in the drawing), and other components that support the electronic control function of the electric control box 100. The side wall 113 of the box body 110 can be provided with a through hole, and a connection cable inside the accommodation cavity 114 of the box body 110 can be led out to the outside of the box body 110 through the through hole; an inlet pipeline and outlet pipeline of the heat dissipation tube inside the accommodation cavity 114 of the box body 110 can also be led out to the outside of the box body 110 through the through hole.
As shown in
For example, a surface of the heat dissipation convert plate 1311 contacting with the element to be heat dissipated is a top surface of the heat dissipation convert plate 1311, and the surface of the element to be heat dissipated contacting with the heat dissipation convert plate 1311 is a bottom surface of the element to be heat dissipated. When the bottom surface of the element to be heat dissipated is a plane, the top surface of the heat dissipation convert plate 1311 can be set as a plane; when the bottom surface of the element to be heat dissipated is concave, the top surface of the heat dissipation convert plate 1311 can be set as a convex surface that matches the concave surface at the bottom surface of the element to be heat dissipated; when the bottom surface of the element to be heat dissipated is convex, the top surface of the heat dissipation convert plate 1311 can be arranged as a concave surface that matches the bottom surface of the element to be heat dissipated, to ensure that the top surface of the heat dissipation convert plate 1311 closely fits the bottom surface of the element to be heat dissipated, to improve a thermal conductivity between the heat dissipation convert plate 1311 and the element to be heat dissipated.
In one embodiment, thermal conductive silicone grease can be applied between the top surface of the heat dissipation convert plate 1311 and the bottom surface of the element to be heat dissipated, to further improve the thermal conductivity between the heat dissipation convert plate 1311 and the element to be heat dissipated, which is beneficial for further improving the heat dissipation efficiency and heat dissipation effect of the heat dissipation plate 130.
The shape and size of the top surface of the heat dissipation convert plate 1311 can be set according to the shape and size of the bottom surface of the element to be heat dissipated. In a possible implementation mode of the embodiment of the present disclosure, the shape and size of the top surface of the heat dissipation convert plate 1311 can be the same as the shape and size of the bottom surface of the element to be heat dissipated, to maximize the contact area between the top surface of the heat dissipation convert plate 1311 and the bottom surface of the element to be heat dissipated, and to further improve the thermal conductivity between the heat dissipation convert plate 1311 and the element to be heat dissipated.
In other possible implementation modes of the embodiment of the present disclosure, a projection of the top surface of the heat dissipation convert plate 1311 on the installation plate 140 can also be set to fall within a projection range of the bottom surface of the ready-for-heat-dissipation element on the installation plate 140 according to an actual need; or, the projection of the bottom surface of the ready-for-heat-dissipation element on the installation plate 140 can be set to fall within the projection range of the top surface of the heat dissipation convert plate 1311 on the installation plate 140 according to an actual need.
In a specific implementation, the heat dissipation plate 130 and the installation plate 140 are assembled together, and the heat dissipation convert plate 1311 on the heat dissipation plate 130 penetrates through the avoidance hole 141 on the installation plate 140 and extends to a side of the installation plate 140 for installing the element to be heat dissipated. Some elements to be heat dissipated, such as a presser and a fan, can be mounted on the heat dissipation convert plate 1311, and the heat dissipation convert plate 1311 can directly contact the element to be heat dissipated. Thus, through the heat dissipation convert plate 1311, the heat dissipation plate 130 can directly cool the element to be heat dissipated, which is conducive to improving the heat dissipation efficiency of the heat dissipation plate 130, improving the heat dissipation effect of the heat dissipation plate 130, and avoiding a problem that the temperature rises due to heat accumulation inside the electric control box 100 and, in turn, the electric control box 100 cannot work normally.
The electric control box 100 provided in the embodiments of the present disclosure involves arranging the heat dissipation plate 130 and the installation plate 140 inside the electric control box 100 in layers, and providing a ready-for-heat-dissipation on the side of the installation plate 140 facing away from the heat dissipation plate 130, and the heat dissipation plate 130 can effectuate heat dissipation for the ready-for-heat-dissipation element provided on the installation plate 140. At the same time, by providing a heat dissipation convert plate 1311 on a side of the heat dissipation plate 130 facing the installation plate 140, and providing an avoidance hole 141 at a position of the installation plate 140 corresponding to the heat dissipation convert plate 1311, and the heat dissipation convert plate 1311 can penetrate through the avoidance hole 141 and come into contact with the element to be heat dissipated, and the heat dissipation plate 130 can better cool the element to be heat dissipated, which is conducive to improving the heat dissipation effect of the heat dissipation plate 130 inside the electric control box 100.
As shown in
The heat dissipation convert plate 1311 can be provided on the limit convert plate 131. After the relative position between the limit convert plate 131 and the avoidance hole 141 is stabilized, the relative position between the heat dissipation convert plate 1311 and the installation plate 140 can be determined, which is conducive to ensuring the relative stability between the element to be heat dissipated and the heat dissipation convert plate 1311, and thus ensuring that the top surface of the heat dissipation convert plate 1311 is in contact with the bottom surface of the element to be heat dissipated, to ensure a thermal conductivity between the element to be heat dissipated and the heat dissipation convert plate 1311, and improve the heat dissipation effect.
It can be understood that the side of the heat exchange tube 120 facing away from the installation plate 140 is provided with a heat exchange tube 120. The heat exchange tube 120 can take away heat on the heat dissipation plate 130, which renders the temperature of the heat dissipation plate 130 to be relatively low. When the air inside the box body 110 come into contact with the heat dissipation plate 130 having a relatively low temperature, condensate water will form on a surface of the heat dissipation plate 130. A contact between the condensate water and the ready-for-heat-dissipation element on the installation plate 140 will affect the performance of the ready-for-heat-dissipation element, and even cause damage to the ready-for-heat-dissipation element.
In order to solve a problem that condensate water accumulating on the heat dissipation plate 130 affects the performance of the element to be heat dissipated, a discharge structure can be provided around the heat dissipation convert plate 1311 in the electric control box 100 provided in the embodiment of the present disclosure, and the condensate water accumulated on the heat dissipation plate 130 can be discharged under the guide of the discharge structure, to avoid excessive condensate water accumulated on the heat dissipation plate 130 from contacting the element to be heat dissipated, and to ensure the performance of the element to be heat dissipated, which is beneficial to ensure a normal operation of the electric control box 100.
As shown in
For example, after the installation of the electric control box 100 is completed, if a first end of the heat dissipation convert plate 1311 is higher than a second end of the heat dissipation convert plate 1311, the first end of the heat dissipation convert plate 1311 is an end thereof facing the water flow direction. At this time, the drainage surface 1312 can be arranged at the first end of the heat dissipation convert plate 1311. In one embodiment, after the installation of the electric control box 100 is completed, if the second end of the heat dissipation convert plate 1311 is higher than the first end of the heat dissipation convert plate 1311, the second end of the heat dissipation convert plate 1311 is the end facing the water flow direction. At this time, the drainage surface 1312 can be arranged at the second end of the heat dissipation convert plate 1311. In order to increase the flexibility of the heat dissipation plate 130 during installation and use, drainage surfaces 1312 can be provided at both ends of the heat dissipation convert plate 1311 of the heat dissipation plate 130. This not only allows the installation position of the heat dissipation plate 130 to be changed according to an actual need, but also allows the installation position of the electric control box 100 to be changed according to actual needs; and thus, ensuring that the condensate water on the heat dissipation plate 130 can be discharged smoothly.
As shown in
In one implementation mode of the embodiments of the present disclosure, the drainage surface 1312 can be an arc-shaped surface, where a middle of the arc-shaped surface bents toward the water flow direction, and the condensate water that flows to the end face of the heat dissipation convert plate 1311 facing the water flow direction can flow to both sides of the arc-shaped surface and finally be discharged.
In another implementation mode of the embodiment of the present disclosure, the drainage surface 1312 is a folded surface, where a middle of the folded surface bends facing the water flow direction. For example, the folded surface may include a V-shaped surface formed by two planes sinking and extending from the middle to both sides; it can also include multiple planes that are sunk and spliced from the middle to both sides, as long as the shape of the folded surface can meet the requirements of bending in the middle facing the water flow direction, and the condensate water can flow toward both sides.
As shown in
As shown in
For example, two side walls 113 of the heat dissipation convert plate 1311 can be formed as groove walls of the discharge groove 1313 arranged on both sides of the heat dissipation convert plate 1311, and the end face of the heat dissipation convert plate 1311 facing the water flow direction can be formed as the drainage surface 1312. At this time, the two sides of the end face of the heat dissipation convert plate 1311 facing the water flow direction are connected to the two side walls 113 of the heat dissipation convert plate 1311 to form a discharge structure around the heat dissipation convert plate 1311. This not only facilitates the discharge of condensate water around the heat dissipation convert plate 1311, but also helps to protect the element to be heat dissipated, and does not require additional processing of the side surface of the discharge groove 1313, which simplifies the structure of the heat dissipation plate 130. For example, the bottom of the discharge groove 1313 can be a flat surface, a concave V-shaped surface, or a concave curved surface, which is conducive to accelerating the accumulation and discharge of the condensate water.
In a specific application, when the condensate water on the heat dissipation plate 130 flows to the end face of the heat dissipation convert plate 1311 facing the water flow direction, the drainage surface 1312 can divert the condensate water to both sides of the drainage surface 1312 to allow the condensate water to flow into the discharge groove 1313. The discharge groove 1313 then draws the condensate water downwards to discharge the condensate water, to prevent an excessive accumulation of condensate water from contacting with the element to be heat dissipated.
The two ends of the discharge groove 1313 along the water flow direction can both extend to the edge of the limit convert plate 131, and the condensate water on the heat dissipation plate 130 can enter the discharge groove 1313 through one end of the discharge groove 1313 facing the water flow direction, and then flow to the other end of the discharge groove 1313 towards the water flow direction under the guide of the discharge groove 1313, to enable the condensate water to be quickly and thoroughly discharged. At the same time, the installation position of the heat dissipation plate 130 can be changed according to actual needs, without affecting the discharge of the condensate water.
As shown in
As shown in
A block 1314 can be provided between two adjacent heat dissipation convert plates 1311; the block 1314 can extend along the water flow direction to an edge of the limit convert plate 131; the discharge groove 1313 is formed between the side surface of the block 1314 along the water flow direction and the heat dissipation convert plate 1311 which is arranged at this side. For example, the side wall 113 of the heat dissipation convert plate 1311 close to the block 1314 and the side wall 113 of the block 1314 close to the heat dissipation convert plate 1311 jointly define a range of the discharge groove 1313, which not only facilitates the discharge of the condensate water, but also helps to reduce a distance between the heat dissipation plate 130 and the element to be heat dissipated, or increase a contact area between the heat dissipation plate 130 and the element to be heat dissipated; and to improve the heat dissipation efficiency.

During an installation of the heat dissipation plate 130 on the heat exchange tube 120, the positioning notch 132 of the heat dissipation plate 130 can be clamped with a positioning structure on the heat exchange tube 120 to achieve pre-positioning of the installation of the heat dissipation plate 130, which is beneficial to improve the installation efficiency.
